Product Description

Climashield Roof Coating is used to renew the look of ageing, porous concrete roof tiles. Superior to a roof paint, it will transform the look of old concrete roof tiles and acts as a waterproof roof paint sealer as well as a coloured roof coating.

Smartseal Climashield Roof Coating is currently available in Anthracite, Slate Grey, Terracotta, Deep Tan, Rustic Red, Burgundy, Mahogany and Black. Once applied, the waterproof roof paint or roof paint sealer will aesthetically transform the roof, leave it water resistant and protect it from the harmful effects of UV light. Once dry, the concrete tiles will be left looking beautiful and benefit from many years of protection against the weather. The waterproof roof paint will also help the roof tiles to slow down the regrowth of moss, algae and lichen. 

Water-vapour permeable coating allowing the roof to 'breathe'. This importantly enables the roof tiles to expel moisture from the inside out. If any roof coating or roof sealer is applied that does not enable this to occur, harmful fungal infections and mould growth can become widespread.

Our waterproof roof paint products are coloured with the highest quality pigments available, the benefits of this include greater resistance to colour deterioration from UV light and excellent adhesion between roof coating and tile.

The roof coating will also allow 'flexing' and movement within the roof tile. Technically this is highly important because exposure to heat and cold will cause roof tiles to expand and contract.





Thoroughly clean roof with pressure washer and treat with concentrate of biocide such as moss clear or moss clear pro. Ensure roof is totally clean, dry and free from moss, algae or lichen spores. Apply only to dry surface. Ensure roof coating is thoroughly mixed prior and during use with no sediment present. Apply by Airless Sprayer to dry surface, with no rain forecast for at least 4 hours. Two coats should be applied. Average coverage of the roof paint sealer is 4m - 6m per litre dependant on porosity of tile, ambient temperature and weather conditions.

Product FAQs

Q: Hi Can I use climashield on concrete roof

Mohammad azam

A: Climashield Roof Coating is formulated for use on concrete roof tiles.

Response from George

Q: Hi, I have my roof painted with climashield a year now but on the north facing side I'm starting to get green growth, can you tell me what product is best to apply to remove any algae that's climashield safe? Thanks


A: Even new roof tiles will have green growth and algae form on them if they damp for long enough. An application of our 'Green Clear' product, will not only treat the green growth, it will also act as a preventative. Hope that helps.

Response from Alex

Q: What make and model airless sprayer would you recommend and what is the tip size?


A: Our contractors generally use wagner or graco machines we believe. Each would be available with a variety of tip sizes.
